Capacitive push-button switch CHT3-1

reinforcedIP69KNO

Product description
The capacitive pushbutton sensor CHT3-1 (dynamic) provides a touch-activated output pulse of approximately 300 ms. With a large actuation area of Ø 50 mm and a compact overall diameter of 88 mm with only 7 mm profile height, it is designed for flexible integration in machine and plant engineering.
The unit is fixed with three screws; different colored cover rings in glass-fibre reinforced polycarbonate can be fitted to hide the screws. The fully potted electronics make the CHT3 extremely robust and 100% water- and oil-tight (IP69K), suitable for harsh industrial environments.
